All,
Here's my situation:
I'm running W2k Server SP3, the OS was currently a 4Gb SCSI disk that I *tried* to mirror onto a 18Gb SCSI disk (on same chain). I also have a 160Gb RAID-0 array on a Promise TX-2000 IDE RAID card.
Now following the instructions I went ahead and 'Upgraded' my disks to Dynamic in order to use the fault tolerence features. After it went through and did its thing it then rebooted, then failed to a BSOD stating a Session3 Initilization error. Thinking it was a fluke I tried rebooting a number of times with no luck. After that I tried to use all the safe modes,repair consoles,etc all with no luck.
So, thinking the worst I went ahead and reinstalled W2k on top of my original disk hoping it would just be able to 'see' the other disks without issue.
Well, as it turns out, the second OS disk that I was trying to mirror to is seen as a Basic disk with no problems, but my RAID array is seen as a Foreign Dynamic disk. Thinking I could just Import it into the new install I went ahead and tried that, but it comes up with the following error:
Internal Error - Disk group has no valid configuration copies
Now I know that when you use Dynamic disks it makes a small partition at the end of your disk for database info (8mb worth). But, when I look at my Array in the Computer Manager it looks like a Basic Disk with one large partition (like it's always been) which would indicate it's not a Dynamic disk.
That all that being said I messed around with dmdiag to look at the actual partitions and from what I can see it is in fact is one large partition set for type 0x42 which is Dynamic.
So, I'm thinking what happened is that it only got far enough to flag the disk Dynamic without actually changing the partition info and that if I go in with DiskProbe and change the type back to 0x07 (Basic) that I'll be able to recover it.
Has anyone out there run into the same kind of situation? If so what did you do? Were you able to fix it? Does my idea have a snow balls chance?
Thanks in Advance!
